A Washington woman who was wearing a short dress and no underwear is facing an indecent exposure charge after allegedly “humping” lawn chairs, exposing herself to a woman and two children, and urinating in public, according to police.

Sila Hans, 33, was arrested earlier this month by cops responding to a report of “an intoxicated female exposing herself and urinating on the lawn” of a Seattle residence.

A female witness told officers that Hans, seen above, “had come onto her lawn and was ‘humping’ the lawn chairs,” according to a Seattle Police Department report. The woman added that she and her two children--ages 15 and 11--watched Hans’s late-afternoon performance from a window in their home.

After grinding on the lawn chairs, Hans allegedly “exposed her vagina,” and then “smacked” her genitals “with her hand multiple times.” Additionally, the witnesses reported that Hans relieved herself on the lawn and “bent over and exposed her bottom.”

Cops who confronted Hans reported that she was “extremely intoxicated” and “displaying erratic behavior.” She was “wearing a short dress with no underwear,” noted Officer Nicolas Olsen, who arrested Hans for indecent exposure.
